采用随机区组设计,进行沼肥与厩肥、复合肥、不施肥4个处理对核桃各项生产指标的影响比较试验,结果表明,施沼肥增产效益显著,且能很好地防治虫害.施沼肥与施厩肥相比平均单株产量提高18.3％,与施复合肥相比平均单株产量提高10.6％.喷施沼液的核桃树树叶虫口率仅为2％,与喷施清水、复合肥及畜粪尿溶液相比,虫口率分别减少36.3％,23.1％和18.4％.%By using a randomized block design, (our tests effect of biogas fertilizer, manure, compound lerlilizer and non-fertilized were studied on walnut yield. The results showed that biogas fertilizer could prevent pests and the yield of walnut was increased significantly. The average yield per plant by applying biogas fertilizer increased up to 18. 3% and 10.6% respectively, compared with applying manure and compound fertilizer, lnsects' population rale on walnut tree leaves was only 2% when spraying biogas slurry, and decreased 36.3% , 23. 1% and 18.4% respectively, compared with spraying water, compound fertilizer and manure solution.
